MAGNETO.

To all whom it may concern:

Be it known that We, LUTHER JAMES SEVI- SON and LUTHER EARLSnvrsonycitizens of theUnited- States, and residents of Elkhart, countyof Elkliart,-and State of Indiana, have invented a certain usefulMagneto; and we do .hereby declare that the following isa full, clear,and exact description thereof,

reference being had to the accompanying drawings.

The-object of this inventionis to provide an improved magneto generatorwhich may be used to furnish current for the ignition of internalcombustion engines.

The features of the invention lie in provid ing a spring contact pointwhich will always make contact at very high speeds together with anadjustable'yoke, whereby the sparksmay be advanced or retarded and thecircuit breaker kept in perfect time with the armature and a disk camcircult breaking dev ce. A further feature is an o ling device,

' whereby the parts of the magneto are kept perfectly oiled.

' The nature of the invention will be understood from the accompanyingdrawings and the following description and claims:

. In the drawings Figure 1 is a vertical longitudinal section midway ofthe device. Fig. 2 is an elevation of the collecting end with the coverremoved. Fig. 3 is a left end elevation of the device. shown in sectionin Fig.

' 1. Fig. 4 is a side elevation of the collecting and 12 and one end 18is adapted to be'driven from any convenient source, of power and theother end isprovided with a collecting device, whereby the currentgenerated-in the armature be collected and delivered for use as it isdesired. The armature 14: is of the common shuttle-wound type with oneterminal oft-he winding connected through the shaft 15 and insulatedtherefrom by the insulation .20 to a binding post 21 on the cover of themachinethrough a flexible connection 121. armature winding is groundedon the frame of the-armature. The bearing 16 for the Specification ofLetters Patent.

collector end of the armature has an outward hub-like projection 22which furnishes bearmg for an oscillatable circuitbreaker 23. Thiscircuit breaker may be oscillated about its hub by means of a yoke 25secured to the circuit breaker by a clamp 26 with stops 27 provided inthe end plate 11 to limit the movement of said yoke. Insulatably mountedon said breaker body a bracket 28 is secured by. screws 29, said bracketextending at right angles to the breaker body and having on its outerend an arced portion 30 with a contact screw 31 mounted thereon. A flatspring 32 is secured at one end to the breaker body 23 and has a contactpoint 3 1 adapted to make contact with the screw 31. Lying against thebreaker body and behind the spring 32, though'not making contact withit, a second spring 36 is secured which may limit the backward movementor free movement of said spring The arced portion 30 mounted on thebreaker body has electrical connection through a brush i0, shown in Fig.i, insulatably mounted 011 the casing 41 to a binding post d2 alsoinsulatably mounted 011 the casing ail, see also Fig. i.

A disk 37 is rigidly secured to the armature shaft and has twodiametrically opposed projections 38 extending on the side toward andadapted when the armature shaft is revolved to meet a projection on thespring 32 and cause the contact point 34 on said spring to leave thecontact screw 31 and thus break the circuit.

Oil passing from the armature bearing will pass. to the disk cam 37 andwill be thrown outward by centrifugal force and keep the wearing pointswell oiled on the cam and the contact spring but a shield secured to thearced portion 30 of the circuit breaker, extending about the disk 37 andlying between it and-the contact screw 31, provents anyoil from beingthrown against the screw and keeps the contactpoints from being fouled.In addition to the oil shield 85, an oil wiper 188 is provided tocollect the oil from the perimeter of the disk. This wiper is secured tothe breaker body and extends outwardly therefrom past the disk 37.

The casing 11 is secured in place by means of the-thumb nut on the endof the'rod 91 extending from the end plate 11.

' Wife claim as our invention:

1. A magneto electric generator including a shaft, a circuit breakerframe mounted so as to be oscillated about said shaft for cri theadjustment, a fiat contact spring mounted on said frame in a directionsubstan tially at a right angle with said shaft, a contact screwmountedfixedly on said frame in position to be engaged by said spring,

contact under the normal action of the spring, a disk secured on theshaft having lateral projections, and projection on the spring adaptedto be engaged by the pro jections on said disk whereby the springccntactwill be moved away from the contact screw periodically.

2. A magneto electric generator includ ing a shaft, a circuit breakerframe mount ed so as to be oscillated about said shaft for theadjustment, a flat contact spring mounted on said frame in a directionsub-- stantially at a right angle with said shaft, a contact screwmounted fixedly on said frame in position to be engaged by said springcontact under the normal action of the spring, a disk secured on theshaft having lateral projections, a projection on the spring adapted tobe'engaged by the procicns on said disk whereby the spring contact willbe moved away from the contactscrew periodically, and a fender platesecured to said frame and heldadjacent portion. the periphery of saiddisk and between the disk and contact points, whereby the Contact pointswill be protected from oil or the like being thrown centrifugally fromsaid disk.

3. A- magneto electric generator including a shaft; a circuit breakerframe mounted so asto be oscillated about said shaft for the adjustment,a flat contact spring mounted on said frame in a direction substantiallyat a right angle with said shaft," a contactscrew mounted fixedly onsaid frame in position to be engaged by said spring contact under thenormal action of the spring, a disk secured on said shaft with a lateralprojection, a projection on the sprlng adapted to be engaged by theprojection on the disk for actuating the copies of. can patentmay beobtained for dive cents cac tuereof, mounted in said bar in pc on to beengaged by he spring cont' when the spring is released, and fend ratecured to said bracket and on partially about the periphery of 2 21' tand between the diskand said contact po'u.v
